Parodies
Episode 295-A of Sgt. Frog titled features the members of the Keroro Platoon finding an artifact that allows two of them to combine into a single Keroro, each with new powers. The episode title is based on Kamen Rider W's catchphrase and the resultant transformation resembles that of Kamen Rider W (the characters appear to be split down the middle, with one side being, for example, Keroro and the other Tamama).
